The Marvell/Marvell multi-gige PHY can also do rate
adaptation. Marvell buying Aquantia made naming messy :-(
I should probably use part numbers.

This patchset enables 2.5Gbps speed mode for stmmac.
Link speed mode is detected and configured at serdes power up sequence.
For 2.5G, we do not use SGMII in-band AN, we check the link speed mode
in the serdes and disable the in-band AN accordingly.
Changes:
v1 -> v2
patch 1/2
